inital refactor commit

Removed Ubuntu from install option.

added case for installing yum if centos cookbook, ubuntu and apt if
installing ubuntu cookbook. (I know I removed ubuntu so there's no
need for a case, this is for testing since I might use ubuntu for
testing if it works as I get centos up to snuff).

Added install python2.7 from source.

Cookbook currently does not work.
fixed yum epel problem, still won't build
